Stopper for a hydraulic dashpot

摘要

A stopper for a hydraulic dashpot for a motor vehicle. The dashpot essentially comprises a piston and cylinder. The cylinder is occupied by fluid and is divided into two chambers by a piston. The piston is mounted on the end of a rod that travels into and out of the cylinder. The stopper is mounted at the end of the cylinder the piston rod travels in and out of. The stopper accommodates seals and several annular components, and at least one of the annular components is attached to the wall of the cylinder. The stopper has an annular component in the shape of a cup at the piston-rod entry-and-exit end. The base of the cup-shaped annular component extends radially inward and has a circular hole at the center. The piston rod extends through the hole. The side of the cup-shaped annular component extends toward the interior of the cylinder. The cup-shaped annular component also accommodates an annular piston-rod aligning component that is at least partly surrounded by the cup-shaped annular component. The annular rod-aligning component has an axially concentric circular cutout for the piston rod to travel in and out through.
